Firmware upgrade and downgrade using a USB mass storage device

Konftel 800 uses the USB mass storage device to support firmware upgrade and
downgrade without the web interface. When you connect the USB mass storage
device to Konftel 800, the phone starts auto-mounting and finds the firmware file
stored on the USB mass storage device. The auto-mounting and parsing process
takes up to 30 seconds depending on your flash drive.
Before performing upgrade or downgrade, the phone does not compare the
firmware version on the USB mass storage device and the currently used firmware
version.
If the firmware file is invalid, the phone shows the following message: Invalid
upgrade file.
The phone starts the upgrade or downgrade procedure immediately if it is in
Idle Mode. Otherwise, Konftel 800 ends an active operation and then starts the
upgrade process.
It is impossible to make calls or enter any menu on the phone during the
upgrade.
Konftel 800 blocks the upgrade procedure using the USB mass storage
device, if the phone already starts the upgrading procedure using the Device
Management provisioning server.
The phone supports several USB flash drive file systems including FAT32 and
NTFS.
Konftel 800 supports only one partition USB flash drives for the upgrade.
